Abstract
By applying ellipsometric analysis, the relationship between the growth of Ag/sub 2/S film and exposure to a H/sub 2/S gas environment was clarified with respect to the contact resistance and formation of the film. Parameters for corrosion kinetics were deduced that are concerned with the growth laws of Ag/sub 2/S film. Furthermore, the effects of oil films on the corrosion resistance of an Ag surface were examined. Stearic acid was used as the oil specimen. The influence of the thickness of the oil film on the contact resistance property was studied for a clean Ag surface and for the surface exposed to an H/sub 2/S gas environment. The optimum thickness for the oil film to sustain low contact resistance was found.<>
